PTC Resettable Fuses Application Field and Working Principle

PTC Resettable Fuses (also known as polyfuses, polymeric positive temperature coefficient (PPTC) fuses) are a type of protection element for electrical circuits that have a number of benefits over other methods of circuit protection. This type of fuse has become increasingly popular in many different industries due to its ability to provide rapid protection for circuits while remaining cost-effective.The 0805L150SLYR is a PTC Resettable Fuse with 0805s, 150V, SL and Y ratings. It is an 8mm x 5mm, 150V resettable fuse with a rated current of 0.05A. It is designed to meet the UL 94V-0 standard and is UL approved. It is suitable for a wide range of applications including automotive, telecom, consumer, computer and industrial.The 0805L150SLYR PTC resettable fuse offers a number of benefits over traditional fuses and circuit protection solutions. Firstly, it is extremely fast-acting, meaning it can respond to faults and short circuits in milliseconds. This response time is much faster than traditional fuses, making the 0805L150SLYR ideal for sensitive applications where circuit protection is paramount.The 0805L150SLYR also offers superior current handling capabilities compared to traditional fuses. This means that it can safely operate under higher current surges, allowing it to protect circuits from spikes and surges.The 0805L150SLYR PTC resettable fuse operates on the principle of resetting itself after a fault or short-circuit has been identified and cleared. This is done by using a PPTC element which is basically a temperature sensitive resistor. When the current passes through the PPTC, the element heats up and will eventually reach its trip point, which is where the PPTC element will open and trigger the circuit protection. After the over-current situation or fault has been cleared, the PPTC will cool down and then reset itself, allowing the current to flow through the circuit again.In summary, the 0805L150SLYR PTC Resettable Fuse is a fast and cost-effective solution for protecting circuits from transient over-currents and short-circuits. It offers superior current handling capabilities compared to traditional fuses, and is capable of responding to faults in milliseconds. Additionally, it has a UL 94V-0 standard rating and is UL approved, making it a safe and reliable choice for many different applications.
